Abstract (en)

[origin: EP1139125A2] An image forming apparatus includes a number of light emitting elements capable of emitting light beam onto a photosensitive material based on given image information, a number of optical fibers extending between a light source and the light emitting elements for guiding light irradiated from the light source to the light emitting elements, each of the optical fibers having a light receiving end for receiving the irradiated light, and a cooling blower device for cooling the receiving ends of the optical fibers with gas stream. In order to cope with a phenomenon of dust becoming accumulated on the light receiving ends of the optical fibers, there is provided a controller 7 operable to execute a pre-blowing/cooling step of operating the cooling blower device 90 for a predetermined period before the light source 15 is turned ON in response to an ON instruction. <IMAGE>
